feature request: aligned_realloc

[Jeff Hammond]

I don't see aligned_realloc anywhere in jemalloc.  I wonder if this is
a feature you would be willing to support?  A colleague of mine was
interested in it recently, and it wasn't obvious how one would do an
efficient implementation on top of the standard API calls.

There are other implementations of this already.  While I am nothing
resembling a fan of Windows, I would argue that a function signature
compatible with MSVC is desirable.

Is this a reasonable request?  I don't feel qualified to implement
this, otherwise I really would try to do it myself and contribute the
patch.

Thanks,

Jeff
